Sažetak
A field trial was setup on experimental field of the Tobacco Institute Zagreb with tobacco monocropping (fertilized and unfertilized tobacco) and with tobacco in crop rotations with maize, soybean, wheat and oil rape. Water leached through the soil to a 50 cm depth was caught by the installed zero tension pan lysimeters. Nitrogen fertilizer rates amounted to 30 kg ha-1 for tobacco, 160 kg ha-1 for wheat, 180 kg ha-1 for maize, 50 kg ha-1 for soybean and 150 kg ha-1 for oil seed rape. Nitrate leaching from fertilizers applied to test crops amounted to 7 &#8211 ; 9.5% while total quantities ranged from 10.8 kg/ha in tobacco monocropping to 27.5 kg ha-1 of nitrate nitrogen in maize growing in crop rotation. Total amounts of nitrate nitrogen leached depended on the amount and distribution of rainfall during the growing season, soil conditions, crop type, and on the applied mineral fertilizer rate.
